Yes. A faint possibility. Buy a set of pregnancy test kits. They work a lot better than guessing.
If you bleed during pregnancy it's not menstruation. It can sometimes seem like it but it's not. And it's usually lighter. If you are menstruating however you can not be pregnant. You menstruate because the uterus is shedding the lining since no egg is fertilized and attached to it. When pregnant you do not release eggs and the uterus can not shed the lining since then you would have a miscarriage.
The endometrial lining.
Wait. The brown discharge is "left over" lining from your previous period. That is why it is brown (think about how dried blood looks). The fact that the old lining is being expelled most likely means you will start your period soon, probably noted by the arrival of red (fresh) lining. Of course, if you are concerned that you are pregnant you could go ahead and take a test.
menstruation
It is what covers the walls of the uterus. When you are ovulating the eggs from the ovaries buries inside of the lining, if you are pregnant the baby grows in the lining, but if you aren't pregnant the lining comes out with blood hence menstruation ( periods)
Ah, you did loose your lining. That what the bleeding was, so most likely you aren't pregnant.
Menstruation results in the discharge of the uterus lining, consisting of blood and tissue.
an inflammation of the mucous membrane lining the nose (usually associated with nasal discharge)
This is normal and natural. http://en.wikipedia.org/wiki/Menstruation
Because if you did you would experience a miscarriage. Your period is the vaginal lining coming off and passing out, this is controlled by hormones. Once you are pregnant the settles into the vaginal lining and uses it as a sort of life support. If you get your period while the zygote is within the lining it will be put out with the lining.
If you have a D and C while pregnant the fetus will be aborted. A D and C stands for the uterus to be dialated and the lining to be cut. or scraped to rid the uterus of the lining
It is called menstruation, or more commonly called a period.
